I keep wanting to build a Tesla coil. Something on the scale of the one Tesla had in Colorado Springs:

I don’t really see that happening.  I am working on a smaller, more transportable one. The lathe at the ITP shop was a helpful fixturing tool for winding this small secondary coil on a piece of PVC.  It could have been wound more comfortably sitting in a chair at home. But in my mind it was an excuse to use the lathe.
